Can"t enable anything above DMA(33) on my SIS5513 equipped laptop

I've got a Packard Bell Easynote H5315 laptop. It contains an SIS5513
IDE controller.

Attached to it is a 60GB "SAMSUNG MP0603H" disk as hda, and a "_NEC
DVD+/-RW ND-6500A" DVD/CD ReWriter as hdc.

I can't seem to enable anything above UDMA2 for the HDD, and when I
burn CDs the drive attempts to run at 10x and the whole machine starts
becoming unresponsive - the mouse pointer in X jerks around, sound
stops and the buffer status of the CD drive jumps up and down.

I've tried doing "hdparm -Xudma5 /dev/hda", but when I type 'dmesg' I
get the following:

ide0: Speed warnings UDMA 3/4/5 is not functional.

Is this a driver problem since surely people still can't be making new
computers that don't support drive speeds above UDMA2... I bought the
laptop in December, so it's relatively new.

Now the thing I've noticed (and it's pasted at the bottom of this
email) is that the drive is connected to the motherboard with a
40-wire IDE cable. Is this because 80-wire laptop IDE cables don't
exist, or has someone tried to save money?

Is there any way I can make my drive faster?

I can't find anything useful on that page... I don't see that DMA error.

After poking around my machine and the web, it seems the speed warning
message is created because my machine doesn't appear to have an
80-wire IDE cable connecting the hard drive to the motherboard.

Since both the drive and the hard drive are ATA133 compliant, and it's
a laptop so the IDE cable will be about five inches long, isn't there
some way I can make it think there's an 80 wire cable present?

The bios isn't that helpful, and adding "ide0=ata66" to my GRUB
command line doesn't do anything. Attempting to set the drive's speed
above UDMA2 still results in the speed warning.

The actual IDE controller is a SIS963.
